- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt (enhances all the flavors)
- 2 large eggs (room temperature works best)
- 1 cup whole milk (or your preferred milk alternative)
- ½ cup vegetable oil (can substitute with melted coconut oil)

3. Step-by-Step Instructions
Step 1: Prepare Dry Ingredients
Preheat your oven to 350°F (175°C) and position the rack in the center. In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. This crucial step ensures your easy chocolate peanut butter cake will have a smooth, lump-free texture and even rise. For an extra pro tip, whisk the dry ingredients after sifting to ensure everything is perfectly combined.

Step 2: Mix Wet Ingredients
In a separate bowl or stand mixer fitted with the paddle attachment, beat the eggs, milk, oil, and vanilla extract on medium speed for about 2 minutes until well combined and slightly frothy. For an extra peanut butter flavor boost, you can add 2 tablespoons of peanut butter to the wet mixture at this stage. If you love peanut butter desserts, you might also enjoy our pumpkin cupcakes with peanut butter frosting or peanut butter kiss cookies.

Step 3: Combine Ingredients
With the mixer on low speed, gradually add the dry ingredients to the wet mixture in three additions, mixing just until combined after each. Be careful not to overmix – this can lead to a tough cake texture. Finally, carefully stir in the boiling water – the batter will be quite thin, but don’t worry! This is the secret to our simple chocolate peanut butter cake’s incredible moistness. For another ultra-moist cake option, try our Easter birds nest cookies or no-bake lemon blueberry dessert.

Step 4: Bake the Cake
Pour the batter into a greased 9×13 inch baking pan (you can also line with parchment paper for easy removal). For an even bake, give the pan a gentle tap on the counter to release any air bubbles. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs. The cake should spring back when lightly touched. Let your quick chocolate peanut butter cake cool completely in the pan on a wire rack before frosting – this usually takes about 2 hours.

4. Peanut Butter Frosting
The crowning glory of this easy chocolate peanut butter cake is the luscious peanut butter frosting. Here’s what you’ll need:
- ½ cup unsalted butter, softened to room temperature
- 1 cup creamy peanut butter (not natural style for best consistency)
- 2 cups powdered sugar, sifted
- ¼ cup heavy cream or whole milk
- 1 teaspoon vanilla extract
- Pinch of salt (balances the sweetness)
In a large bowl using a hand mixer or in the bowl of a stand mixer fitted with the paddle attachment, beat the butter and peanut butter together on medium speed until completely smooth and creamy, about 2 minutes. Add the powdered sugar, cream, vanilla, and salt. Start mixing on low speed until incorporated, then increase to high speed and beat for 2-3 minutes until light and fluffy. If the frosting is too thick, add more cream 1 tablespoon at a time. If too thin, add more powdered sugar ¼ cup at a time. Spread over the completely cooled cake using an offset spatula and garnish with chocolate shavings, chopped peanuts, or even peanut butter cups if you’re feeling extra indulgent!
5. Baking Tips for Perfect Results
- Room temperature ingredients blend together more easily and create a smoother batter
- Proper measuring is key – spoon flour into measuring cups and level off with a knife
- Don’t overmix the batter – stop as soon as ingredients are combined to avoid a dense cake
- For extra moistness, brush the baked cake with simple syrup (equal parts sugar and water heated until dissolved) before frosting
- For stronger peanut flavor, swirl additional peanut butter into the batter before baking or add ½ cup chopped peanuts
- Oven thermometer ensures accurate temperature since oven dials can be off by 25°F or more
6. Storage Instructions
Store your simple chocolate peanut butter cake covered with plastic wrap or in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. The flavors actually develop more over time, making this quick chocolate peanut butter cake even more delicious the next day! The frosting will firm up when chilled, so let the cake sit at room temperature for 30 minutes before serving if refrigerated.
For longer storage, you can freeze the unfrosted cake layers wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the refrigerator before frosting and serving. The frosted cake can also be frozen for up to 1 month – freeze uncovered first until the frosting is firm, then wrap tightly.
7. Variations to Try:
- Chocolate chips: Fold 1 cup semi-sweet or milk chocolate chips into the batter
- Marble cake: Reserve 1 cup of batter, mix with ¼ cup peanut butter, then swirl through the chocolate batter
- Chocolate ganache: Top with chocolate ganache instead of or in addition to the peanut butter frosting
- Cupcakes: Bake as cupcakes for 18-22 minutes – perfect for parties!
- Layer cake: Double the recipe and bake in two 9-inch round pans for an impressive layer cake
- Peanut butter cups</strong: Press mini peanut butter cups into the frosting for decoration
- Banana version: Add 1 cup mashed ripe bananas to the batter for a chocolate-peanut butter-banana combo
8. Frequently Asked Questions
Q: Can I use natural peanut butter in this recipe?
A: While you can use natural peanut butter, we recommend conventional peanut butter like Jif or Skippy for both the cake and frosting. Natural peanut butters tend to separate and can make the frosting less stable. If using natural peanut butter, look for a “no-stir” variety and consider adding an extra ¼ cup powdered sugar to the frosting to help stabilize it.
Q: Can I make this cake gluten-free?
A: Absolutely! Substitute the all-purpose flour with your favorite 1:1 gluten-free flour blend. We’ve had great results with Bob’s Red Mill and King Arthur gluten-free blends. The texture may be slightly denser but still delicious. For more gluten-free options, browse our cookie recipes.
Q: How do I know when the cake is done baking?
A: The cake is done when: 1) The edges pull away from the pan slightly, 2) The center springs back when lightly touched, and 3) A toothpick inserted in the center comes out clean or with just a few moist crumbs. Be careful not to overbake as this will dry out your cake.
Q: Can I make this cake dairy-free?
A: Yes! Use your favorite non-dairy milk (almond, soy, or oat milk work well) and substitute the butter in the frosting with vegan butter or coconut oil. The cake itself is naturally dairy-free except for the milk, which is easily substituted.
Q: Why is boiling water added to the batter?
A: The boiling water serves two purposes: 1) It helps “bloom” the cocoa powder, intensifying its chocolate flavor, and 2) It creates an ultra-moist cake texture by fully hydrating the flour. Don’t worry – the batter will be thin but bakes up perfectly!
